Edwards Air Force Base

Edwards Air Force Base is a United States Air Force installation in California. Most of the base sits in Kern County, but its eastern end is in San Bernardino County and a southern arm is in Los Angeles County. The hub of the base is Edwards, California. Established in the 1930s as Muroc Field, the facility was renamed Muroc Army Airfield and then Muroc Air Force Base before its final renaming in 1950 for World War II USAAF veteran and test pilot Capt. Glen Edwards.
Edwards is the home of the Air Force Test Center, Air Force Test Pilot School, and NASA's Armstrong Flight Research Center. It is the Air Force Materiel Command center for conducting and supporting research and development of flight, as well as testing and evaluating aerospace systems from concept to combat. It also hosts many test activities conducted by America's commercial aerospace industry.
Notable occurrences at Edwards include Chuck Yeager's flight that broke the sound barrier in the Bell X-1, test flights of the North American X-15, the first landings of the Space Shuttle, and the 1986 around-the-world flight of the Rutan Voyager.

History

Origins

A water stop on the Santa Fe Railroad since 1882, the site was largely unsettled until the early 20th century. In 1910, Ralph, Clifford and Effie Corum built a homestead on the edge of Rogers Dry Lake. The Corums proved instrumental in attracting other settlers and building infrastructure in the area, and when a post office was commissioned for the area, they named it Muroc, a reversal of the Corum name, due to the presence of a town named Coram.
Conscious that March Field was located in an area of increasing growth in Riverside County, and with the need for bombing and gunnery ranges for his units, base and 1st Wing commander Lieutenant Colonel Henry H. "Hap" Arnold began the process of acquiring land next to Muroc Dry Lake for a new bombing range away from populated areas in August 1932; the last tract was not acquired until 1939. The facility established to support the range, initially called "Mohave Field" for the nearby community of Mohave, was Muroc Field. In October 1935, five men under a Sergeant Folgleman were sent to the area from March Field. They put out circular bombing targets in the desert. For the next two years aircraft shuttled back and forth between Muroc Dry Lake and March Field for Crew Bombing Practice.
At this time, another colorful character in Edwards' history, Pancho Barnes, built her renowned Rancho Oro Verde Fly-Inn Dude Ranch that would be the scene of many parties and celebrations to come. The dry lake was a hive of hot rodding, with racing on the playa. The runway on which the Space Shuttle landed follows the route that hosted racing in the 1930s.
The first major aerial activity occurred at Muroc in 1937 when the entire Army Air Corps participated in a large-scale maneuver. From then on, the bombing range grew in size. When Arnold became Chief of the Air Corps in 1938, the service was given a renewed focus on research and development. Muroc Field drew attention because the nearby dry lake was so flat that it could serve as a giant runway, ideal for flight testing. Over US$120 million was spent to develop the base in the 1940s and expand it to. The base's main runway was completed in a single pour of concrete.

World War II

On the afternoon of 7 December 1941, the 41st Bombardment Group and the 6th Reconnaissance Squadron moved to Muroc from Davis-Monthan Army Airfield, Arizona, with a collection of Douglas B-18 Bolos, North American B-25 Mitchells, and an A-29 Hudson. On Christmas Eve, the 30th Bombardment Group and the 2d Reconnaissance Squadron arrived from New Orleans Army Airbase, Louisiana, for crew training. On 23 July 1942, the Muroc Bombing and Gunnery Range, Muroc Lake, California, was designated as a separate post. The name of the facility at the time was "Army Air Base, Muroc Lake."
In July 1942, Muroc Army Airfield became a separate airfield from March Field and was placed under the jurisdiction of Fourth Air Force. Throughout the war years, the primary mission at Muroc was providing final combat training for bomber and fighter aircrews just before overseas deployment. Among its sub-bases and auxiliaries were:

Muroc was initially used for IV Bomber Command Operational Unit training. The North American B-25 Mitchell 41st and 30th Bombardment Groups and the Douglas A-20 Havoc 47th Bombardment Groups trained at the station in early 1942. The training provided newly graduated pilots eight to 12 weeks of training as a team using the same aircraft they would use in combat. In 1942, the training mission was transferred to IV Fighter Command, with Lockheed P-38 Lightning OTU training for the 78th and 81st Fighter Groups. In 1943, the 360th Fighter Group and 382d Bombardment Groups were assigned permanently to Muroc for P-38 Lightning and B-24 Liberator Replacement Training of personnel.
In the spring of 1942, the Mojave Desert station was chosen as a secluded site for testing America's first jet, the super-secret Bell Aircraft P-59 Airacomet jet fighter. The immense volume of flight tests being conducted at Wright Field, in Ohio, helped drive a search for a new, isolated site where a "Top Secret" airplane could undergo tests "away from prying eyes." The urgent need to complete the P-59 program without delay dictated a location with good, year-round flying weather, and the risks inherent in the radical new technology to be demonstrated on the aircraft dictated a spacious landing field. After examining a number of locations around the country, they selected a site along the north shore of the enormous, flat surface of Rogers Dry Lake about six miles away from the training base at Muroc.
Ground tests began five days after the first XP-59 arrived on 21 September 1942. First flight took place on 30 September when the XP-59 rose to altitude for during taxi testing. However, the first official flight was 1 October 1942 with NACA, Navy Bureau of Aeronautics, Royal Air Force, Army, Bell and General Electric personnel on hand.
As with virtually all of the test programs conducted during the war years, most of the actual flight test work on the P-59 was conducted by the contractor. Although Army Air Forces pilots flew the aircraft from time to time, and flight test engineers from Wright Field reviewed the data, the formal preliminary military test and evaluation program did not commence until the fall of 1943, a year after the first flight. Designed to validate the contractor's reports, this preliminary evaluation consisted of a very limited number of flights and was essentially completed within a month. Formal operational suitability and accelerated service tests did not get underway until 1944, well after the AAF had decided that the airplane would not be suitable for combat operations and would, instead, be relegated to a training role.
The P-59s were tested at Muroc from October 1942 through February 1944 without a single accident and, though the aircraft did not prove to be combat worthy, the successful conduct of its test program, combined with the success of the Lockheed XP-80 program which followed it in early 1944, sealed the future destiny of the remote high desert installation. Muroc would thenceforth become synonymous with the cutting edge of the turbojet revolution in America.
Aircraft testing continued at this desert "Army Air Base", then on 8 November 1943, the base title was changed to "Muroc Army Air Field, Muroc". In the fall of 1944, Eighth Air Force ran tests to determine how well conventional fighters stood up against jets. Also, in October 1944, a small detachment arrived at the base for experimental work in rocket firing and achieved such success that they remained through most of 1945.
Other World War II test flights included the Northrop JB-1 Bat.
In 1943, a replica of a Japanese cruiser, nicknamed "Muroc Maru", was constructed in Rogers Dry Lake where it was used for bombing training until 1950.

Postwar era

With the end of the war, Fourth Air Force relinquished command of Muroc Army Airfield on 16 October 1945 and jurisdiction was transferred to Air Technical Service Command, becoming Air Materiel Command in 1946. Test work on the Lockheed P-80 Shooting Star was the primary mission of the base for the greater part of the fall of 1945. The Consolidated Vultee XP-81 single-seat, long-range escort fighter and Republic XP-84 Thunderjet fighter arrived at the base in early 1946 for flight testing. It was obvious even at this embryonic stage of base development that the Army Air Force desert station was destined to become a proving ground for aircraft and a testing site for experimental airplanes.
The success of these programs attracted a new type of research activity to the base in late 1946. The rocket-powered Bell X-1 was the first in a long series of experimental airplanes designed to prove or disprove aeronautical concepts—to probe the most challenging unknowns of flight and solve its mysteries. Further evidence of things to come was experienced on 14 October 1947 when Captain Charles "Chuck" Yeager flew the small bullet-shaped airplane to become the first human to exceed the speed of sound.
Four months later, on 10 February 1948, Muroc AAF was re-designated Muroc Air Force Base with the establishment of the United States Air Force as a separate military service. Units attached or assigned to the base at the time were the 4144th Army Air Force Base Unit, the 3208th Strategic Bomb Test Squadron along with communications and weather detachments. On 20 August 1948, the 4144th Air Force Base Unit was re-designated as the 2759th AF Base Unit and with the adoption of the Hobson Plan, as the 2759th Experimental Wing.
With the X-1, flight testing at Muroc began to assume two distinct identities. Highly experimental research programs—such as the X-3, X-4, X-5 and XF-92A—were typically flown in conjunction with the National Advisory Committee for Aeronautics, or NACA, and were conducted in a methodical fashion to answer largely theoretical questions. Then, as now, the great bulk of flight testing at Muroc focused on evaluations of the capabilities of aircraft and systems proposed for the operational inventory.

In December 1949, Muroc was renamed Edwards Air Force Base in honor of Captain Glen Edwards, who was killed a year earlier in the crash of the Northrop YB-49 Flying Wing. During World War II, he flew A-20 Havoc light attack bombers in the North African campaign on 50 hazardous, low-level missions against German tanks, convoys, troops, bridges, airfields, and other tactical targets. Edwards, from Alberta, Canada, became a test pilot in 1943 and spent much of his time at Muroc Army Air Field, on California's high desert, testing wide varieties of experimental prototype aircraft. He died in the crash of a Northrop YB-49 flying wing near Muroc AFB on 5 June 1948. From the time Edwards Air Force Base was named, speed and altitude records began to pile up as new aircraft were developed and the base started to build and branch out significantly.
A major reason for the growth of Edwards AFB was the nearness of West Coast aircraft manufacturers. However, another major reason was the decision in 1947 to build a missile test facility on the base. The need for a static missile faculty to test high-thrust missile rocket engines was first envisioned in 1946 by the Power Plant Laboratory at Wright-Patterson Air Force Base. It was that decision that such a facility should be government-owned to prevent a single contractor exclusive advantages on Air Force contracts for high-thrust missile rocket power plants, and it would eliminate duplication of like facilities by different manufacturers. The choice of location in 1947 was the Leuhman Ridge east of Rogers Dry Lake on Edwards AFB. Construction began in November 1949 on what was to become the Experimental Rocket Engine Test Station.
